Guangzhou Onyx Information Technology Co., Ltd., known as Onyx Boox, submitted a new listing application to the Hong Kong Stock Exchange on September 23, according to exchange disclosures. China Securities (International) acts as the sole sponsor for this IPO attempt. This marks the company's second filing, following an earlier submission on January 16, 2026.

The company describes itself as a global consumer electronics brand operating in the knowledge-focused productivity tools sector. Onyx Boox designs intelligent hardware devices that aim to replicate paper-like reading and writing experiences, emphasizing focus and portability to help knowledge workers efficiently access written content. These devices support tasks such as summarizing, searching, editing, and managing information, allowing users to present high-value output.

Onyx Boox's product lineup consists of two main categories: high-speed e-readers and productivity tablets. Both run on the company's proprietary open operating system, BOOXOS. According to Frost & Sullivan data, based on retail value in 2025, Onyx Boox ranks as the largest knowledge-focused productivity tool brand in China and the second-largest globally. This segment forms part of the broader knowledge-focused smart device market, contributing nearly half of that market's overall retail value in 2025. The same research indicates that Onyx Boox holds a 4.2% global market share in its segment, while the leading competitor commands a 13.1% share.
